BACKGROUND

In the current Internet there exist many different types of media assets in the form of digital files. Digital files may contain data representing one or more types of content, including but not limited to, audio, images, and videos. For example, media assets include file formats such as MPEG-1 Audio Layer 3 (“MP3”) for audio, Joint Photographic Experts Group (“JPEG”) for images, Motion Picture Experts Group (“MPEG-2” and “MPEG-4”) for video, Adobe Flash for animations, and executable files.

Such media assets are currently created and edited using applications executing locally on a dedicated computer. For example, in the case of digital video, popular applications for creating and editing media assets include Apple's iMovie and FinalCut Pro and Microsoft's MovieMaker. After creation and editing a media asset, one or more files may be transmitted to a computer (e.g., a server) located on a distributed network such as the Internet. The server may host the files for viewing by different users. Examples of companies operating such servers are YouTube (http://youtube.com) and Google Video (http://video.google.com).

Presently, users must create and/or edit media assets on their client computers before transmitting the media assets to a server. Many users are therefore unable able to edit media assets from another client where, for example, the user's client computer does not contain the appropriate application or media asset for editing. Moreover, editing applications are typically designed for professional or high-end consumer markets. Such applications do not address the needs of average consumers who lack dedicated computers with considerable processing power and/or storage capacity.

Additionally, average consumers typically do not have the transmission bandwidth necessary to transfer, share or access media assets that may be widespread across a network. Increasingly, many media assets are stored on computer connected to the Internet. For example, services such as Getty Images sell media assets (e.g., images) that are stored on computers connected to the Internet. Thus, when a user requests a media asset for manipulation or editing, the asset is typically transferred in its entirety over the network. Particularly in the case of digital video, such transfers may consume tremendous processing and transmission resources.

SUMMARY

Against this backdrop systems and methods have been developed for manipulating media assets in a networked computing environment where processing power, bandwidth and/or storage capacity may be limited. More specifically, systems and methods have been developed whereby low-resolution media assets may be created that are optimized for transfer over low bandwidth networks and for editing and manipulation in an environment with low processing power and low storage capacity, and a high-resolution media asset may be created for playback.

DETAILED DESCRIPTION

FIG. 1 illustrates an embodiment of a system 100 for generating a media asset. In one embodiment, a system 100 is comprised of a master asset library 102. In one embodiment, a master asset library 102 may be a logical grouping of data, including but not limited to high-resolution and low-resolution media assets. In another embodiment, a master asset library 102 may be a physical grouping of data, including but not limited to high-resolution and low-resolution media assets. In an embodiment, a master asset library 102 may be comprised of one or more databases and reside on one or more servers. In one embodiment, master asset library 102 may be comprised of a plurality of libraries, including public, private, and shared libraries. In one embodiment, a master asset library 102 may be organized into a searchable library. In another embodiment, the one or more servers comprising master asset library 102 may include connections to one or more storage devices for storing digital files.

For purposes of this disclosure, the drawings associated with this disclosure, and the appended claims, the term “files” generally refers to a collection of information that is stored as a unit and that, among other things, may be retrieved, modified, stored, deleted or transferred. Storage devices may include, but are not limited to, volatile memory (e.g., RAM, DRAM), non-volatile memory (e.g., ROM, EPROM, flash memory), and devices such as hard disk drives and optical drives. Storage devices may store information redundantly. Storage devices may also be connected in parallel, in a series, or in some other connection configuration. As set forth in the present embodiment, one or more assets may reside within a master asset library 102.

For purposes of this disclosure, the drawings associated with this disclosure, and the appended claims, an “asset” refers to a logical collection of content that may be comprised within one or more files. For example, an asset may be comprised of a single file (e.g., an MPEG video file) that contains images (e.g., a still frame of video), audio, and video information. As another example, an asset may also may be comprised of a collection of files (e.g., JPEG image files) that collectively may be used to render an animation or video. As yet another example, an asset may also comprise an executable file (e.g., an executable vector graphics file, such as an SWF file or an FLA file). A master asset library 102 may include many types of assets, including but not limited to, video, images, animations, text, executable files, and audio. In one embodiment, master asset library 102 may include one or more high-resolution master assets. For the remainder of this disclosure, “master asset” will be disclosed as a digital file containing video content. One skilled in the art will recognize, however, that a master asset is not limited to containing video information, and as set forth previously, a master asset may contain many types of information including but not limited to images, audio, text, executable files, and/or animations.

In one embodiment, a media asset may be stored in a master asset library 102 so as to preserve the quality of the media asset. For example, in the case of a media asset comprising video information, two important aspects of video quality are spatial resolution and temporal resolution. Spatial resolution generally describes the clarity of lack of blurring in a displayed image, while temporal resolution generally describes the smoothness of motion. Motion video, like film, consists of a certain number of frames per second to represent motion in the scene. Typically, the first step in digitizing video is to partition each frame into a large number of picture elements, or pixels or pels for short. The larger the number of pixels, the higher the spatial resolution. Similarly, the more frames per second, the higher the temporal resolution.

In one embodiment, a media asset may be stored in a master asset library 102 as a master asset that is not directly manipulated. For example, a media asset may be preserved in a master asset library 102 in its original form, although it may still be used to create copies or derivative media assets (e.g., low-resolution assets). In one embodiment, a media asset may also be stored in a master asset library 102 with corresponding or associated assets. In one embodiment, a media asset stored in a master asset library 102 may be stored as multiple versions of the same media asset. For example, multiple versions of a media asset stored in master asset library 102 may include an all-keyframe version that does not take advantage of intra-frame similarities for compression purposes, and an optimized version that does take advantage of intra-frame similarities. In one embodiment, the original media asset may represent an all-keyframe version. In another embodiment, the original media asset may originally be in the form of an optimized version or stored as an optimized version. One skilled in the art will recognize that media assets may take many forms within a master asset library 102 that are within the scope of this disclosure.

In one embodiment, a system 100 is also comprised of an edit asset generator 104. In an embodiment, an edit asset generator 104 may be comprised of transcoding hardware and/or software that, among other things, may convert a media asset from one format into another format. For example, a transcoder may be used to convert an MPEG file into a Quicktime file. As another example, a transcoder may be used to convert a JPEG file into a bitmap (e.g., *.BMP) file. As yet another example, a transcoder may standardize media asset formats into an Flash video file (*.FLV) format. In one embodiment, a transcoder may create more than one versions of an original media asset. For example, upon receiving an original media asset, a transcoder may convert the original media asset into a high-resolution version and a low-resolution version. As another example, a transcoder may convert an original media asset into one or more files. In one embodiment, a transcoder may exist on a remote computing device. In another embodiment, a transcoder may exist on one or more connected computers. In one embodiment, an edit asset generator 104 may also be comprised of hardware and/or software for transferring and/or uploading media assets to one or more computers. In another embodiment, an edit asset generator 104 may be comprised of or connected to hardware and/or software used to capture media assets from external sources such as a digital camera.

In one embodiment, an edit asset generator 104 may generate a low-resolution version of a high-resolution media asset stored in a master asset library 102. In another embodiment, an edit asset generator 104 may transmit a low-resolution version of a media asset stored in a master asset library 102, for example, by converting the media asset in real-time and transmitting the media asset as a stream to a remote computing device. In another embodiment, an edit asset generator 104 may generate a low quality version of another media asset (e.g., a master asset), such that the low quality version preserves while still providing sufficient data to enable a user to apply edits to the low quality version.

In one embodiment, a system 100 may also be comprised of a specification applicator 106. In one embodiment, a specification applicator 106 may be comprised of one or more files or edit specifications that include instructions for editing and modifying a media asset (e.g., a high-resolution media asset). In one embodiment, a specification applicator 106 may include one or more edit specifications that comprise modification instructions for a high-resolution media asset based upon edits made to a corresponding or associated low-resolution media asset. In one embodiment, a specification applicator 106 may store a plurality of edit specifications in one or more libraries.

In one embodiment, a system 100 is also comprised of a master asset editor 108 that may apply one or more edit specifications to a media asset. For example, a master asset editor 108 may apply an edit specification stored in a specification applicator 106 library to a first high-resolution media asset and thereby creates another high-resolution media asset, e.g., a second high-resolution media asset. In one embodiment, a master asset editor 108 may apply an edit specification to a media asset in real-time. For example, a master asset editor 108 may modify a media asset as the media asset is transmitted to another location. In another embodiment, a master asset editor 108 may apply an edit specification to a media asset in non-real-time. For example, a master asset editor 108 may apply edit specifications to a media asset as part of a scheduled process. In one embodiment, a master asset editor 108 may be used to minimize the necessity of transferring large media assets over a network. For example, by storing edits in an edit specification, a master asset editor 108 may transfer small data files across a network to effectuate manipulations made on a remote computing device to higher quality assets stored on one or more local computers (e.g., computers comprising a master asset library).

In another embodiment, a master asset editor 108 may be responsive to commands from a remote computing device (e.g., clicking a “remix” button at a remote computing device may command the master asset editor 108 to apply an edit specification to a high-resolution media asset). For example, a master asset editor 108 may dynamically and/or interactively apply an edit specification to a media asset upon a user command issuing from a remote computing device. In one embodiment, a master asset editor 108 may dynamically apply an edit specification to a high-resolution to generate an edited high-resolution media asset for playback. In another embodiment, a master asset editor 108 may apply an edit specification to a media asset on a remote computing device and one or more computers connected by a network (e.g., Internet 114). For example, bifurcating the application of an edit specification may minimize the size of the edited high-resolution asset prior to transferring it to a remote computing device for playback. In another embodiment, a master asset editor 108 may apply an edit specification on a remote computing device, for example, to take advantage of vector-based processing that may be executed efficiently on a remote computing device at playtime.

In one embodiment, a system 100 is also comprised of an editor 110 that may reside on a remote computing device 112 that is connected to one or more networked computers, such as the Internet 114. In one embodiment, an editor 110 may be comprised of software. For example, an editor 110 may be a stand-alone program. As another example, an editor 110 may be comprised of one or more instructions that may be executed through another program such as an Internet 114 browser (e.g., Microsoft Internet Explorer). In one embodiment, an editor 110 may be designed with a user interface similar to other media-editing programs. In one embodiment, an editor 110 may contain connections to a master asset library 102, an edit asset library 104, a specification applicator 106 and/or a master asset editor 108. In one embodiment, an editor 110 may include pre-constructed or “default” edit specifications that may be applied by a remote computing device to a media asset. In one embodiment, an editor 110 may include a player program for displaying media assets and/or applying one or more instructions from an edit specification upon playback of a media asset. In another embodiment, an editor 110 may be connected to a player program (e.g., a standalone editor may be connected to a browser).

FIG. 2 illustrates an embodiment of a system 200 for generating a media asset. In one embodiment, the system 200 comprises a high-resolution media asset library 202. In one embodiment, the high-resolution media asset library 202 may be a shared library, a public library, and/or a private library. In one embodiment, the high-resolution media asset library 202 may include at least one video file. In another embodiment, the high resolution media asset library 202 may include at least one audio file. In yet another embodiment, the high-resolution media asset library 202 may include at least one reference to a media asset residing on a remote computing device 212. In one embodiment, the high-resolution media asset library 202 may reside on a plurality of computing devices.

In one embodiment, the system 200 further comprises a low-resolution media asset generator 204 that generates low-resolution media assets from high-resolution media assets contained in the high-resolution media asset library. For example, as discussed above, a low-resolution media asset generator 204 may convert a high-resolution media asset to a low-resolution media asset.

In one embodiment, the system 200 further comprises a low-resolution media asset editor 208 that transmits edits made to an associated low-resolution media asset to one or more computers via a network, such as the Internet 214. In another embodiment, the low-resolution media asset editor 208 may reside on a computing device remote from the high resolution media asset editor, for example, remote computing device 212. In another embodiment, the low-resolution media asset editor 208 may utilize a browser. For example, the low-resolution media asset editor 208 may store low-resolution media assets in the cache of a browser.

In one embodiment, the system 200 may also comprise an image rendering device 210 that displays the associated low-resolution media asset. In one embodiment, an image rendering device 210 resides on a computing device 212 remote from the high-resolution media asset editor 206. In another embodiment, an image rendering device 210 may utilize a browser.

In one embodiment, the system 200 further comprises a high-resolution media asset editor 206 that applies edits to a high-resolution media asset based on edits made to an associated low-resolution media asset.

FIG. 3 illustrates an embodiment of a method 300 for editing a low-resolution media asset to generate a high-resolution edited media asset. In the method 300, a request to edit a first high-resolution media is received from a requester in a requesting operation 302. In one embodiment, the first high-resolution media asset may be comprised of a plurality of files and receiving a request to edit the first high-resolution media asset in requesting operation 302 may further comprise receiving a request to edit at least one of the plurality of files. In another embodiment, requesting operation 302 may further comprise receiving a request to edit at least one high-resolution audio or video file.

In the method 300, a low-resolution media asset based upon the first high-resolution media asset is transmitted to a requestor in a transmitting operation 304. In one embodiment, transmitting operation 304 may comprise transmitting at least one low-resolution audio or video file. In another embodiment, transmitting operation 304 may further comprise converting at least one high-resolution audio or video file associated with a first high-resolution media asset from a first file format into at least one low-resolution audio or video file, respectively, having a second file format. For example, a high-resolution uncompressed audio file (e.g., a WAV file) may be converted into a compressed audio file (e.g., an MP3 file). As another example, a compressed file with a lesser compression ratio may be converted into a file of the same format, but formatted with a greater compression ratio.

The method 300 then comprises receiving from a requestor an edit instruction associated with a low-resolution media asset in receiving operation 306. In one embodiment, receiving operation 306 may further comprise receiving an instruction to modify a video presentation property of at least one high-resolution video file. For example, modification of a video presentation property may include receiving an instruction to modify an image aspect ratio, a spatial resolution value, a temporal resolution value, a bit rate value, or a compression value. In another embodiment, receiving operation 306 may further comprise receiving an instruction to modify a timeline (e.g., sequence of frames) of at least one high-resolution video file.

The method 300 further comprises generating a second high-resolution media asset based upon the first high-resolution media asset and the edit instruction associated with the low-resolution media asset in a generating operation 308. In one embodiment of generating operation 308, an edit specification is applied to at least one high-resolution audio or video file comprising the first high-resolution media asset. In a further embodiment, generating operation 308 generates at least one high-resolution audio or video file. In another embodiment, generating operation 308 further comprises the steps of: generating a copy of at least one high-resolution audio or video file associated with a first high-resolution media asset; applying the edit instruction, respectively, to the at least one high-resolution audio or video file; and saving the copy as a second high-resolution media asset.

In another embodiment of method 300, at least a portion of the second high-resolution media asset may be transmitted to a remote computing device. In still yet another embodiment of method 300, at least a portion of the second high-resolution media asset may be displayed by an image rendering device. For example, the image rendering device may take the form of a browser residing at a remote computing device.

FIG. 4 illustrates an embodiment of a method 400 for generating a media asset. In the method 400, a request to generate a video asset, the video asset identifying a starting frame and an ending frame in a keyframe master asset, is received in receiving operation 402.
